Note:
There is a gap between the top and bottom halves of the circle because each half
is a separate function. The mathematical endpoints of each half are (
L
5,0) and (5,0).
4. Define y2(x) =
, the function for
the bottom half of the circle.
The bottom half is the negative of the top
half, so you can define y2(x) =
L
y1(x).
Use the full function name
y1(x)
, not
simply y1.

5. Select the
ZoomStd
viewing window,
which automatically graphs the
functions.
In the standard viewing window, both the
x and y axes range from
L
10 to 10.
However, this range is spread over a
longer distance along the x axis than the
y axis. Therefore, the circle appears as
an ellipse.

increases the range along the
x axis so that circles and squares are
shown in correct proportion.
